In order to analyze stress mechanics of corm- gated pipe culvert on the condition of thaw settlement , the paper analyzes mechanical property of metal corm- gated pipe culvert and corrugated pipe in permafrost re- gion with large-scale finite element software.

为分析波纹管涵洞融沉下的受力机理，利用大型有限元软件对多年冻土地区采用的金属波纹管涵洞和波纹管本身进行力学性能分析，通过分析可知，金属波纹管本身具有较大的横向补偿位移的能力，波纹管涵洞对预防和彻底解决涵洞因融沉而导致的破坏较为有效。

In addition, they clearly understand that the problems existing in the current painting circles shall not be ignored and the impacts and negative effects to the high-brow arts from the tide of commercialization and mass media and culture cannot be underestimated.

如何在深入观察、体验、思考和分析现实生活的基础上，沉下心来，在作品的思想深度和艺术语言方面狠下功夫，为社会大众奉献有价值的精神食粮，是包括他们在内的所有艺术家们面临的严肃课题。

The shiplift platform is composed of longitudinal lissome coupling three platform, having 70 meters length, 13 meters width, which has a total lifting ability of 1100 tons. It is rised and lowered depending on 14 sets of winding engines synchronous operation.

该升船机是由纵向柔性联结的三平台构成，总长70米，宽13米，总提升力为1100吨，如何依靠14台卷扬机同步操作实现平台的升起或沉下是研究的要点。

Mace lowered his head into his hands. How have we come to this?

梅斯沉下了头，双手掩面，我们怎么走到这一步了？

A good diver knows when their feet start to drop and risk getting into the silty bottom or coral.
